초록

본 연구는 고품질 비단잉어 생산을 위해 비단잉어와 홍잉어 교배종의 성장과 적색색소의 빈도분석을 통해 비단잉어 색도를 분석하였다. 색소 및 성장도 분석을 위해 부화 후 170일령 비단잉어를 각 교배 집단별로[비단잉어${\times}$비단잉어(KK), 비단잉어${\times}$홍잉어(KR)와 홍잉어${\times}$비단잉어(RK)] 100개체씩 분석하였다. 성장도 분석 결과 비단잉어${\times}$홍잉어(KR) 교배집단에서 전장과 전중의 성장이 가장 높았다. 교배 그룹 모두 흰색, 적색-흰색, 적색의 3가지 색소 패턴을 보였다. 적색색소 분포는 KK 집단이 64%, KR 집단이 56%, RK 집단이 36%였다. 적색 색소 범위의 빈도분석 결과 적색색소 30~50%를 차지하는 비율이 KK 집단이 10%, RK 집단이 12% 그리고 KR 집단이 14%로 가장 높았다. 비단잉어 적색색소 빈도 분석에 관한 연구는 비단잉어 선별을 위한 분석 도구로서 활용이 가능할 것으로 판단된다.

The purpose of this study was to investigate color pattern and growth in cross progenies between kois and red common carp (Cyprinus carpio). Coverage of red color patches in skin was investigated in $koi{\times}koi$ (KK), $koi{\times}red$ common carp (KR) and red common $carp{\times}koi$ (RK) progenies in 170 days post-hatching (DPH) by analysis of digital photographs. KR cross group had higher length (P<0.05) and the mean weight than in the KK but there were no significant difference between KR and RK. All groups consisted of three color pattern white, white-red and red. The percentage of red-area coverage in skin was 64% in KK progenies, 56% in KR and 36% in RK. The red coverage (30~50%) was highly in KR (15%) than in KK (10%) and RK (12%). The application of red-area body coverage analysis may suggest potentially useful tool for ornamental fish selection.
